[Geoserver-users] Some CSS newbie questions

[Roel_De_Nijs]

Good afternoon,

Sometimes SLDs can be quite tedious, so I started a PoC: converting 1 of our biggest SLDs (+4000 lines) using the CSS module. First results are very promising, but I have some questions in order to mimic the existing styling as close as possible. And if exactly the same styling would not be possible, to have an idea about the differences.

1. What’s the equivalent of PropertyIsNull-tag?

2. Does an equivalent of the ElseFilter-tag exist?

3. Combined rules with metadata appear in the legend with the word “with” (e.g. “Parcels with Borders”). Is it possible to configure this behavior (e.g. “Parcels (Borders)”)?

4. It seems the order in which the rules are rendered based on the css is random. Is that true? Or can I influence this order in some way? Otherwise the legend (based on the resulting SLD) is in randomly order.

5. Can I import a css style into another one (cfr. the @import in regular css files)?

6. In the documentation about well-known marks [1] this syntax is used to have a TrueType mark symbol(‘ttf://Times+New+Roman&char=0x19b2’);, but that doesn’t work for me. When I use symbol(‘ttf://Times+New+Roman#0x19b2’); instead (that’s what I used in the original SLD as well), it works like a charm. Could it be a flaw in the documentation?

"myAttribute is null"

2. Does an equivalent of the ElseFilter-tag exist?

None

(e.g. “Parcels with Borders”). Is it possible to configure this behavior
(e.g. “Parcels (Borders)”)?

Nope

4. It seems the order in which the rules are rendered based on the css is
random. Is that true? Or can I influence this order in some way? Otherwise
the legend (based on the resulting SLD) is in randomly order.

I'm not sure sure.. probably no way to control the order

5. Can I import a css style into another one (cfr. the @import in regular
css files)?

No

6. In the documentation about well-known marks [1] this syntax is used to
have a TrueType mark symbol('ttf://Times+New+Roman&char=0x19b2');, but
that doesn’t work for me. When I use
symbol('ttf://Times+New+Roman#0x19b2'); instead (that’s what I used in the
original SLD as well), it works like a charm. Could it be a flaw in the

I believe so, yes

Not really the answers I was hoping for J Some of the answers would be acceptable, others would not be. So the CSS module is unfortunately not useful for us. Will have to stick to the SLDs for now.
